Modern cinema offers various interpretations of the famous novel: from the modern-day action of the series "Sherlock" to the slightly comedic steampunk version by Guy Ritchie, "Sherlock Holmes: A Game of Shadows". And, of course, one must not forget the Soviet classic: the brilliant "Sherlock Holmes and Dr. Watson" with Vasily Livanov. Professor Langdon, portrayed by Tom Hanks, will uncover all the ancient secrets in the films "The Da Vinci Code" and "Angels & Demons," while a famous journalist will retreat to a small island to unravel the secrets of a family in the detective thriller "The Girl with the Dragon Tattoo." Tom Hanks and Leonardo DiCaprio's heroes will play a cat-and-mouse game in the adventurous drama about the great con artist "Catch Me If You Can," while Soviet spies will unravel more than one conspiracy in the film "Spy."
